Annually observed on April 18, 2021, round the world with different types of activities, including visits to monuments and heritage sites, conferences, round tables, and newspaper articles. The aim is to market awareness about the variety of cultural heritage of humanity, their vulnerability, and the efforts required for his or her protection and conservation.

There is a need to ask: what are the concrete actions that require to be taken to integrate cultural heritage conservation and promotion into the sustainable development debate? The term “sustainability” has multiple meanings and uses regarding cultural heritage. Most often, the term is used in conjunction with or as a part of such concepts as sustainable preservation, sustainable development, or sustainable tourism, though these concepts in practice overlap and are closely intertwined.

The objective of Sustainable projects, monuments, or sites is to help owners with sustainability, for instance in lowering energy costs. So, we ask: what measures are needed to push the safeguarding of the cultural heritage within Nigeria or the global development agenda on a broader scale?

There should be an appeal for a project to focus on opportunities and possibilities for monument owners in realizing more sustainable buildings. Development that meets the requirements of the current status quo of sustainability without compromising the flexibility of future generations to satisfy their own environmental needs.

The most effective available techniques also as types of cooperation, financing, and optimizing the method of sustainable renovation/restoration should acutely be put into consideration for effective policies for durable and self-sustainable projects within the cultural heritage sector.
